Aluminum is the most produced and used metal following steel in the world because of its combination of physical properties. Aluminum is produced in two ways; primary aluminum production and secondary aluminum production. The main objectives of this study are to find out waste generation in aluminum industry, to determine waste generation factors(WGFs)and to suggest best available techniquesfor the management of wastes from this activity. Fordetermination of waste generation in primary and secondary aluminum sectors in Turkey, aluminum producers were listed and examined,in terms of their production processes, raw materials, production capacities, waste types and waste generation steps. In addition, field studies were carried out for on-site examination of both primary and secondary aluminum producers. After that, wastes were identified based on literature review and field studiesusing the waste list defined by European Commission as a base (Commission Decision 2000/532/EC).Then, range forWGFsfor both primary and secondary aluminum sectors in Turkey were determined based on literature review, field studies and declared amount of wastes to the Ministry of Environment and Urbanization.When the waste generation in primary and secondary aluminum production was assessed, it isseen thatsecondary aluminum production generates high quantities of hazardous wastes whereas generated amount of total wastes is considerably higher in the primary production.Within the scope of this study, best available techniquesthat can be adopted to the Turkish aluminum industryfor a better management of the wastes generatedwere also investigated.

Thermo-mechanically coupled numerical and experimental study on 7075 aluminum forging process and dies Özcan, Mehmet Cihat; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2008) Combination of high strength with light weight which is the prominent property of aluminum alloy forgings has led aluminum forgings used in rapidly expanding range of applications. In this study, to produce a particular 7075 aluminum alloy part, the forging process has been designed and analyzed. The forging process sequence has been designed by using Finite Volume Method. Then, the designed process has been analyzed by using Finite Element Method and the stress, strain and temperature distributions within ...
Development of cast and heat treated 7075 alloy rifle receiver Güngör, Ahmet Umur; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2015) Developing technology in the world makes products lighter and have higher strength values. That’s why, aluminum and titanium alloys start to be used instead of steel. It can be seen that 7075 aluminum alloy is one of the highest strength amongst the aluminum alloys. This alloy has a close tensile strength value to some steels, with help of the heat treatment applications and developing production technologies. Generally, industrial usage of 7075 alloy is machining of 7075 alloy extrusion slab into desired s...
Development of high strength aluminum matrix composite backing plates for ballistic armor Durmaz, Tayfun; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2017) Recently, aluminum and aluminum alloys have gained great importance in engineering applications by the help of technological developments. Today, it is possible to see aluminum alloys in very different sectors of industry because of their superior properties. Some of these important properties are high specific strength, lightness and ductility. In addition, it has low density, high corrosion resistance and high mechanical properties that make aluminum crucial in transportation, construction, packaging, hou...
Analysis of magnesium addition, hydrogen porosity and T6 heat treatment effects on mechanical and microstructural properties of pressure die cast 7075 aluminum alloy Alat, Ece; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2012) Aluminum alloys are having more attention due to their high specific stiffness and processing advantages. 7075 aluminum alloy is a wrought composition aluminum alloy in the Al-Zn-Mg-Cu series. Due to the significant addition of these alloying elements, 7075 has higher strength compared to all other aluminum alloys and effective precipitation hardenability characteristic. On the other hand, aluminum alloys have some drawbacks, which hinder the widespread application of them. One of the most commonly encounte...
Microstructure hierarchy - Mechanical property relationship for hypereutectic Al-Si alloy powders solidified far from equilibrium Kalay, Yunus Eren; Chumbley, L.s. (2006-12-01) Microstructural selection in aluminum silicon powder alloys can directly influence the consolidated materials' mechanical properties. However, due to processing and characterization difficulties, a complete understanding of powder microstructure as a function of undercooling and solidification velocity, and the role microstructure plays on mechanical properties, remains an elusive goal. In this study high pressure gas atomization processing was used to produce rapidly solidified hypereutectic Al-Si alloys. ...
